Supersymmetry, Large Extra Dimensions and the Gravitino Conjecture
Leonardo Bersigotti, Dieter Lust, Marco Scalisi
We investigate whether the absence of experimental signals for supersymmetry and extra dimensions can be understood as a correlated phenomenon. Assuming the Gravitino Conjecture, w…
Quintessential -attractors fit DESI
Alessandro Borys, Joaquin Masias, Marco Scalisi
We study quintessence in -attractor models in light of recent DESI indications for dynamical dark energy. We show that the \emph{knee} of the attractor potential provides an exc…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Inflationary Particle Production and the Swampland
Dieter Lüst, Joaquin Masias, Mauro Pieroni +1
We investigate the impact of particle production during inflation in scenarios where an infinite tower of states features a mass scale that decreases exponentially along the inflat…
Bulk/boundary Modular Quintessence and DESI
Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +4
The latest DESI DR2 results, when combined with other independent cosmological data on the Cosmic Microwave Background and supernovas, suggest a preference for dynamical dark energ…
On the Origin of Species Thermodynamics and the Black Hole - Tower Correspondence
Alvaro Herráez, Dieter Lüst, Joaquin Masias +1
Species thermodynamics has been proposed in analogy to black hole thermodynamics. The entropy scales like an area and is given by the mere counting of the number of the species. In…
Species Scale and Primordial Gravitational Waves
Marco Scalisi
The species scale is a field-dependent UV cut-off for any effective field theory weakly coupled to gravity. In this letter we show that, in the context of inflationary cosmology, a…
Starobinsky Inflation in the Swampland
Dieter Lust, Joaquin Masias, Benjamin Muntz +1
We argue that the Starobinsky model of inflation, realised via an term in the Lagrangian, can originate from quantum effects due to a tower of light species. By means of two…
Primordial black holes and their gravitational-wave signatures
Eleni Bagui, Sebastien Clesse, Valerio De Luca +17
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain…
Cosmic Acceleration and Turns in the Swampland
Julian Freigang, Dieter Lust, Guo-En Nian +1
We argue that field trajectories, which lead to cosmic acceleration and feature rapid turns near the boundary of the moduli space, are in the Swampland. We obtain this result by as…
Early Dark Energy in Type IIB String Theory
Michele Cicoli, Matteo Licheri, Ratul Mahanta +3
Early Dark Energy (EDE) is a promising model to resolve the Hubble Tension, that, informed by Cosmic Microwave Background data, features a generalization of the potential energy us…
On the correspondence between black holes, domain walls and fluxes
Niccolò Cribiori, Alessandra Gnecchi, Dieter Lust +1
We revisit and extend the correspondence between black holes, domain walls and fluxes in type IIA compactifications. We argue that these three systems can be described by the same…
The Scale of Supersymmetry Breaking and the Dark Dimension
Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +2
We argue for a relation between the supersymmetry breaking scale and the measured value of the dark energy density . We derive it by combining two quantum gravity consistency sw…
Towards Early Dark Energy in String Theory
Evan McDonough, Marco Scalisi
Early Dark Energy (EDE) is a prominent model to resolve the Hubble tension, which employs a dynamical axion with a periodic potential. In this work, we take first steps towards the…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Large and Small Non-extremal Black Holes, Thermodynamic Dualities, and the Swampland
Niccolò Cribiori, Markus Dierigl, Alessandra Gnecchi +2
In this paper we discuss black hole solutions parametrized by their entropy and temperature in gravitational effective theories. We are especially inter…
The Gravitino and the Swampland
Niccolò Cribiori, Dieter Lust, Marco Scalisi
We propose a new swampland conjecture stating that the limit of vanishing gravitino mass corresponds to the massless limit of an infinite tower of states and to the consequent brea…
Conifold dynamics and axion monodromies
Marco Scalisi, Pablo Soler, Vincent Van Hemelryck +1
It has recently been appreciated that the conifold modulus plays an important role in string-phenomenological set-ups involving warped throats, both by imposing constraints on mode…
Inflation, Higher Spins and the Swampland
Marco Scalisi
We study the implications on inflation of an infinite tower of higher-spin states with masses falling exponentially at large field distances, as dictated by the Swampland Distance…
dS Vacua and the Swampland
Renata Kallosh, Andrei Linde, Evan McDonough +1
In this note we revisit some of the recent 10d and 4d arguments suggesting that uplifting of supersymmetric AdS vacua leads to flattening of the potential, preventing formation of…
Swampland Distance Conjecture, Inflation and -attractors
Marco Scalisi, Irene Valenzuela
The Swampland Distance Conjecture (SDC) constraints the dynamics emerging at infinite distances in field space of any effective field theory consistent with quantum gravity. It pro…
4d models of dS uplift in KKLT
Renata Kallosh, Andrei Linde, Evan McDonough +1
It was shown in arXiv:1808.09428 that the modified 4d version of the KKLT model proposed in arXiv:1707.08678 is inconsistent for large values of the parameter advocated in arXi…
de Sitter Vacua with a Nilpotent Superfield
Renata Kallosh, Andrei Linde, Evan McDonough +1
We study the arguments given in [1] which suggest that the uplifting procedure in the KKLT construction is not valid. First we show that the modification of the SUSY breaking secto…
Pole N-flation
Mafalda Dias, Jonathan Frazer, Ander Retolaza +2
A second order pole in the scalar kinetic term can lead to a class of inflation models with universal predictions referred to as pole inflation or -attractors. While this kineti…
